We have the 3011 so I measured and on the 3011 with the U-shaped dinette the storage area of the drawers are:

12 and 1/2 inches wide, 25 inches long and 6 inches high (top to bottom) with an additional 1-1/2 to 2 inches between the top of the drawer and the opening for the drawer so things can go slightly above the height of the drawer and still fit ok.
